Please LABEL the two populations when writing hypothesis statements. 1. There are three main types of exercises: range-of-motion (flexibility), strengthening, and endurance. Researchers would like to estimate the mean workout length for the strengthening with 99% confidence. They have no idea of the population standard deviation so they take a pilot sample of 24 people who exercise regularly and measure how long their strengthening exercise lasts (minutes). The sample mean time was 73.6 minutes and the sample standard deviation was...

Problem 6 A machine produces metal pieces that are cylindrical in shape. A sample of these pieces is taken and the diameters are found to be 1.01, 0.97, 1.03, 1.04, 0.99, 0.98, 0.99, 1.01 and 1.03 centimeters. The sample mean and standard deviation for the given data are i-1.0056 and s = 0.0246. Assume normality. (a) Find a 99% confidence interval on the mean diameter (b) Compute a 99% prediction interval...

A musician is writing a new song and wants to know at which tempo he should write it to break onto the pop music charts. He takes a random sample of 100 pop songs and finds an average tempo of 131.9 bpm with a standard deviation of 14. Where applicable, use 3 decimals in the following answers. Please carry your intermediate calculations out to 4 decimal places. a) Find the upper limit for a 95% confidence interval for the average...
